VTo @ZZ whom it may couoeimf Be it known that LJosErri MAY, a citizen ofthe German Empire, residing at Frankfort-on-the-lifain, Holzsraben2,have invented certain new and useful "Improvements in Pen Cleaners, ofwhich the following is a full, clear, and'exact description, refe-rencebeing had to the-accompanying drawing and to letters of reference markedthereon.

MyV invention relates to a new pen-cleaner. F or pen-cleaners, materialof different kinds for dry and wet use has heretofore been proposed; butthese materials were not satisfactory for wiping the pens and did notaccomplish their purposes. In some cases such materials clog the penswith libres, in consequence of the fibrous nature of said material, orin the case of wet cleaners, a very speedy ruinof the pens by rust hasresulted from their use. To the aforesaid class of dry wiping devicesbelong for ef;- ample, felt, soft leather and the like while the classof wet wiping devices` includes, for instance a sponge fitted in a waterchamber.

The nature of the present invention consists in the use of asponge-rubber for dry wiping of the pens.

F or the purpose referred to, this material is fitted specially owing toits natural qualities. Sponge-rubber is smooth, soft, slippery andporous. It does not unravel, removes the ink and the residues smoothlyand completely from the pen and does not suck up or absorb the ink, likefelt, soft leather or otherV fibrous materials. The ink and the inkresidues wiped from therpen are loosely accumulated upon the surface ofthe sponge-rubber and are therefore very easily 0' washed out andremoved thus making it 4 easy to maintain the cleaner in a serviceablecondition. In consequence of its smooth and slippery-surface thesponge-rubber preserves Vtlie pens against undue wear in cleaning andwipes them completely dry. Moreover they sponge-rubber is furtheradvantageous, because it does not clog the pens with-libres, which causeimperfections in subsequent writing with the aid of said pen.

The accompanying drawing shows two examples of the new pen-cleaner oneof which is for use by hand and the other of which is capable of use byhand or as a standing pen-cleaner upon a writing table or desk. In saiddrawing- Fig. 1 is a section of the pen cleaner for useby hand, and

. Fig. 2 a top view thereof. l y

The pen-cleaner, in the form shown in Figs. l and 2,'jconsist's of twoarched plateshaped parts` a, al, each of which constitutes a body andare covered on the inside with sponge-rubber and which have their convexsurfaces toward each other are held together by an elastic member. Theannular slit formed in this manner for cleaning and wiping the pens maybe compressed by the plateshaped parts at any place, or may be caused tospread or gap at a point opposite to the point at which pressure isexerted to press the plate-shaped parts a and a toward each other. Theexecution of the pressure results in an axial direction.

Instead of the central fastening means, a tension chain may be provided,which tension chain is stretched around the spongerubber so as to extendabout the foot of the cupola. The body itself may be manufactured in anyconvenient manner and of every suitable material and it maysimultaneously serve other purposes, for instance, as a letterpresser orthe like; it may also beused for advertisements.

The yielding, universally pliant, soft and smooth slippery mass of thesponge-rubber, makes it possible to thoroughly clean the pens or thelike with the least wear thereon and with the danger of injuring thesaine or of clogging or otherwise harmfully effecting said pens or thelike reduced to a minimum. The sponge-rubber material, because of itseasy exchangeability, is repeatedly available and is easily cleaned bywashing.

Having thus described my improved pencleaner of sponge-rubber, it willbe seen, i

that it has many advantages over those theretofore in use. lts cost isvery little including the sponge and it is very durable.

claim as invention:

1. A pen-cleaner comprising a pair of elements lying in surfaceengagement with each other, at least one of said elements being ofsponge-rubber and means for resiliently fastening said elements togetherat an intermediate point whereby the surface engagement of said elementsis maintained and the edges thereof are free and disconnected to permita pen to be inserted between said elements and subjected to the cleaningaction of the sponge-rubber.
